Patients were accrued at the VA Chicago Health Care System Lakeside Urology Clinic. Upon consent for participation in the study, comorbidities, histologic grade of the biopsy, and age were obtained for 13 patients with newly diagnosed localized prostate cancer. Using a standard gamble technique, interviewers obtained patient utilities for 5 distinct health states related to prostate cancer treatment. Clinical and pathologic characteristics were incorporated into the decision analytic model, and the derived quality-adjusted life expectancies (QALEs) were shared with the treating urologist before patient-physician discussion of treatment options. The feasibility of the decision analytic intervention and unbiased estimates of the impact of the intervention was evaluated. The long-range objective of this proposal is to design an intervention for veterans that increases physician understanding of patient treatment preferences and patient understanding of choices in prostate cancer treatment.
